Product Description
The JJB Series packs near the performance of a
conventional monopole into an incredibly compact
quarterinch (7mm) diameter package. These
antennas are ideal for any OEM application
requiring a compact, cosmetically attractive,
low-cost antenna solution. The antenna features
a through-hole feedline that can attach directly
to a users PCB. Internal or external mounting is
possible. For assemblies requiring a JJB antenna
capable of withstanding reflow temperatures up to
260癈, see the JJB-HT Series.
Features
